Yandere vs tsundere

If you had to choose between being in a romantic relationship with a tsundere or a yandere, which would you choose, and why?
(Speaking of long term relationships)

There’s no middle ground—you can’t say “both” or choose another deretype. Choose carefully.

Note: and for those of you who is unfamiliar with those terms..

* Tsundere: is Someone who acts cold, harsh, or dismissive toward the person they like but gradually reveals a warm, caring, and affectionate side.

* Yandere: is Someone who appears sweet, loving, and deeply devoted but whose love can become obsessive, possessive, and even dangerous if pushed too far.
